How can you improve your sense of self?

Are we talking mentally or physically? I have found an activity that allows one to work on improving both. It is not a new sport but one that has been around for years, Stand Up Paddleboarding. SUP’ing is quickly becoming one of the fastest growing sports largely due to it’s many health benefits in addition to being low-impact. Stand Up Paddleboarding regularily improves one’s sense of self both mentally and phsyically.
